Rahmel, Evanston, Ill., assignors to A. C. Nielsen Company, Chicago, Ill., a corporation ci' Illinois Application May '1, 1946, Serial No. 666,262 23 claims. (ci. zar-1) The present invention relates to a'statistical analysis system for prime movers such as are employed in mobile vehicles and more particularly to a statistical analysis system by means of which data on the purchases of expendable quantities such as oil or gasoline for prime movers as employed in automotive vehicles maybeobtained substantially without fail for analysis purposes.

Modern merchandlsers spend huge sums of money in advertising their products. In order that they may know whether such sums of money are `well spent it is desirable that they have some satisfactory and fairly accurate'means of analyz- -ing the effectiveness of such advertising. This becomes especially important in a highly competitive field such as is the case, for example, with vendors of oil or gasoline who sell their porducts `directly or indirectly to vtlie operators of oil or gasoline consuming devices such as motor vehicles. vIt would be desirable for such merchandisers to be able to obtain reasonably accurate data relating to oil or gasoline sales in a particlar area by sampling a representative group of operators so that a reliable analysis may be made of such data to determine the effectiveness of advertising campaigns carried on in such area for any particular merchandiser. Apparatus for obtaining such data should be simple, inexpensive and foolproof with regard to obtaining accurately the necessary data. I l

Whenever the operator of a gasoline or oil consuming device such as a motor vehicle, said operator being a part of the statistical sample,

.purchases oil or gas or both he should be reminded by suitable means that such purchase fdata should be recorded. Furthermore the recording of such data should cause him a minimum of inconvenience and should be recorded in such a manner that it may at stated intervals be referred to a suitable organization for analysis without causing any substantial additional inconvenience to the operator of the automotive vehicle or like device.l 4Such statistical analysis systems should be constructed `so they can readily be installed in apparatus such for'example as automotive vehicles of -a selected cross-section of automobile operators in a particular area, for example, where an extensive advertising campaign is to be carried out, whereby accurate data may be obtained both before and after such campaign to give an index or measure of the effectiveness of such advertising.

It is an object of the present invention, therefore. to provide a simple, inexpensive purchase 2 data recording system which will accomplish the ends outlined above.

It is another object of the present invention to provide a new and improved statistical analysis system for apparatus requiring expendable material which includes an annoyance signal means operative when an expendable quantity ofmaterial is supplied to said apparatus.

Another object of the present invention is to provide an effective and inexpensive arrangement for obtaining data regarding purchases of expendable quantities of material for automotive vehicles including means for effectively requiring the purchaser to record such purchase data.

A further object of the present invention is to provide an arrangement for obtaining data. regarding purchases of expendable quantities of `material for prime movers in which the purchaser is reminded to record appropriate data when purchases are made by suitable signal means, but wherein such signal means are rendered ineffective after a predetermined time if the purchaser fails to heed such signal means.

Further objects and advantages of the present invention will become apparent as the following description proceeds and the features of novelty which characterize the present invention will be pointed out with particularity in the claims annexed to and forming a part of this specification.

For a better understanding of the present invention reference may be had to the accompanying drawings in which:

Fig. 1 v'is a perspective view of a recording device embodying the present invention with the recording device shown in position for making a recording;

Fig. 2 is a sectional view taken on line 2 2 of Fig. 1;

Fig. 3 is a sectional view taken on line 3-3 of Fig. l, except with the cover of the recording device illustrated Vin the closed fposition;

Figs. 4 and 5 are partial views illustrating in detail different portions of the recording device of Fig. 1;

Fig. 6 is an exploded perspective viewv of a transportable record assembly employed in the recording device of Fig. 1, together with an associated portion of the recording device of Fig. l; and

Fig. 7 is a. schematic circuit diagram illustratin'g the electrical control system for the recording-device with the cover thereof in the same position as in Fig. 3.

Although the present invention is applicable for use in obtaining data regarding purchases of any expendable material used in operating any apparatus or device, it is particularly adapted for use in obtaining data concerning gasoline or oil purchases for automobiles. and the present invention has been specically illustrated in connection with such an application. It should be understood, however, that its application is not limited to obtaining such specific purchase data.

Referring now to the drawings, there is illustrated a recording device generally indicated at III, comprising a somewhat rectangular shaped substantially closed casing or housing I I, preferably of such dimensions that it may readily iit into the glove compartment of an automotive vehicle or into any relatively small space in such a vehicle. 'I'he housing Il is provided at its upper surface with an opening I2 adapted to be closed by a slidable cover I3 which may be manually actuated by means of a suitable handle I4. The cover I3 is shown in the open position in Figs. l and 2 of the drawings and in the closed position in Figs. 3 and 'I of the drawings. Part of the opening I2 is preferably closed by a glass or plastic heading panel or plate I5 which is preferably illuminated by means of a suitable source of light I6 mounted within the housing II. The light from the source I6 will thus be diffused fromthe edge of the plate I5 w as to illuminate the unclosed portion of the opening I2 which deilnes the recording space. The plate I5 may have suitable indicia thereon as indicated in Fig. 1 of the drawings, to call the purchasers attention to pertinent data which should be recorded.

The recording space defined by the opening I2 in the housing II and limited by the heading panel I5 is further so restricted by a suitable panel I1 as to define a recording space I8 between the edges of the panels I5 and I1 within the opening I2. Both of the panels I5 and I1 are so positioned that the cover I3 may be moved to open or closed positions without interference. The panel I1 includes a depression or trough I3 for accommodating therein a suitable recording instrument 20 which may be an ordinary Writing implement such as a pencil, or may be a steel stylus pencil in the event that recording paper sensitized to a steel stylus is employed. As far as the present invention is concerned, the specific construction of recording implement 20 is immaterial. Preferably this recording implement is attached by suitable means such as a chain 20a shown in Fig. 5 of the drawings, or other suitable means, to the housing II. The writing implement 20 is so positioned in the depression or trough I3 that it does not interfere with movement of the cover I3. In order to hold the recording implement 20 in position and to perform a controlling function which will be described in detail hereinafter, there is provided a suitable clip 2I, best shown in Figs. 6 and 'I of the drawings, which is fastened in the trough or depression I9 of the panel I1.

Preferably, the panel I8 is also provided with a vsmall recording opening 22 closed by a suitable pivotally mounted cover 23. A locking pin 24 is fastened to the free end of the cover 23 and extends into the housing II when the cover 23 is closed. The purpose of the locking pin 24 will become apparent as the following description proceeds. Adjacent the opening 22 on the panel I1 suitable indicia such as Mileage may be inscribed so that the purchaser of the expendable material will recognize the opening 22 as providing access to a recording space for use in recording the mileage reading at periodic intervals.

In order that the recorded purchase data may be made readily available to a data analysis organization, the recording device I0 is provided with a portion thereof in the form of a unitary self-contained transportable record assembly or removable cartridge generally indicated by the reference numeral 25 and best shown in the exploded perspective view of Fig. 6 of the drawings. ',Io accommodate the unitary self-contained record assembly 25, the housing II is provided with an opening at one end thereof closed by a suitable cover 26. The base of the housing II is provided with inwardly extending guide members 21 shown in Figs. 2, 3, 4 and 6 of the drawings between which the record assembly 25 is slidable when inserted or removed through the'opening closed by the coverA 26. The guides 21 are preferably provided with openings 28 wlthin'which are positioned suitable spring fingers or the llike 29 for engaging with cooperating openings 30 in the transportable record assembly so as to removably position the transportable record assembly 25 within the housing II. A

Inasmuch as it is desirable to be able to mail the unitary self-contained transportable record assembly 25 from a collaborator to an analyzing organization in an addressed and stamped container furnished by the analyzing organization, this assembly is constructed to comprise a suitable housing deiined by a base 3|, a rectangular frame 32 and a platen 33 having a downwardly extending web 33' for supporting the platen 33 in its proper position: Within the housing of the transportable record assembly are provided a supply roll or spool 34 and a take-up and drive roll or spool 35 for a recording tape or record strip 36 which is adapted to move over the platen 33 in the manner clearly shown in Fig. 2 of the drawings, whereby recordings may be made on the record strip 36 while positioned on the platen 33. The supply and drive rolls 34 and 35 are rotatably mounted within the rectangular frame 32 of the transportable record assembly 25. If desired, a suitable dished washer 31 may be provided to act as a brake for the supply roll 34. It is obvious that any suitable braking means may be employed forl this purpose and it forms no part of the present invention.

For the purpose of rotating the supply and drive rollers 34 and 35, thereby to move the record strip 36, there is provided in the housing II a ratchet 38 mounted on a shaft 39 rotatably supported in the end wall of the housing I I opposite the opening closed by the cover 26 and between the guides 21. The shaft 39 is provided with a slotted end 40 adapted to mate with the keyed end 4I of the shaft which supports the drive `roller 35. When the transportable record assembly 25 is inserted in the housing I I the slotted and keyed ends 40 and 4I of the shaft 39 and the shaft supporting the drive roller 35, respectively, are interlockingly engaged as shown in Fig. 4 of the drawings, whereby movement of the record strip 36 is obtained upon rotation of the ratchet 38.

In order that the spool 35 may easily be removed from the housing 32 and in order to facilitate proper positioning of the assembly 25 in the housing I I, even though the matching keyed ends of the shaft 39 and the shaft supporting the take-up or drive roller 35 are not in proper alignment, there is provided a stub shaft 42 keyed as indicated at 44 for limited axial movement relative to the shaft 43 of the drive or take-up roller 35 rs as is indicated at u. 'rne stub shaft u is axiauy movable relative to the shaft 43 and is biased to the positionl indicated in Fig. 4 of the drawings by suitable spring means 45. VWith this construction, the spool may upon removal of the platen 33, easily be removedfrom the housing 32 by manually withdrawing the stub shaft 42 from its bearing in the end wall of the housing 82. It is also quite obvious that. when the transportable record assembly 251s inserted in the housing II to the position indicated in Fig. 4 of the drawings with the spring biased fingers 28 interlocking with the openings 30, the stub shaft 42 may be moved in an axial direction relative .to the shaft 43 in the event that the matching keyed ends of the stub shaft 42 and the -shaft 3l are not in alignment. As soon as the ratchet`38 is rotated to align the keyed ends of these shafts then spring will cause stub shaft 42 to aume the position indicated in Fig. 4 of the drawings. It will be obvious that the described arrangement also makes for ready insertion of the shaft 43 into its bearings in the record assembly. To permit removal and replacement of the supply roll 34, the shaft of this supply roll is also preferably constructed in the manner described above to include a spring biased stub shaft 42.

To remind the purchaser of the expendable material upon which purchase data is being obtained to make a mileage recording prior to removal of the transportable record assembly 25 and mailing thereof to the analysis organization for compilation of the data and analysis thereof, this assembly or removable cartridge 25 is provided with a suitable aperture 46 in platen 33 which cooperates with the locking pin 24 associated with the cover 23 referred to above. When the cover 23 is in the closed position covering the opening of the mileage recording portion of the device, the locking pin 24 is inserted in the aperture 46 and the transportable record assembly or removable cartridge 25 is locked in position such that it cannot be, removed without first opening the cover 23.

As clearly shown in Fig. 1 of the drawings. the movable recording tape or record strip 36 is preferably provided with suitable signs or markings to aid the purchaser in recording the\proper data. These markings are preferably related to the indicia provided on the transluscent or transparent panel I5. Suitable means should be provided for advancing the movable record strip 3l following each recording operation and to vthis end,the ratchet 38 is arranged for actuation in response to opening of the cover I3 of the recording device Ill. Specifically and as is best shown in Fig. 3 of the drawings, the cover I3 is provided with a rack 41 pivotally mounted upon the door I3 by suitable axis means 48. A bowed leaf spring 43 biases the rack 41 into engagement with the ratchet 38. Also, a suitable spring biased pawl is mounted within the housing II to engage the teeth of the ratchet 38 so as to prevent rotation in any but the proper direction, which is clockwise as viewed in Fig. 3 of the drawings. Each time the door I3 is moved to the open position, the rack 41 which is biased into engagement with the ratchet 38 by means of the spring 43, is moved to the right as viewed Vin Fig. 3. to produce resultant rotation of the ratchet 38 and movement of the record strip 36 across the platen 33. The ratchet 38 and the rack 41 are so designed and the sets of markings on the strip 38 are so spaced that the successive sets of markings appearing on the record strip will always assume the same position relative to the recording space Il of the housing II in response to successive operations of the cover I3 between its closed and open positions. If there is to be a large variation in the diameter of the take-up spool as more and more of the record strip is wound thereon whereby movement of rack 41 causes an increased increment of paper movement, it may be desirable to vary the spacing between the successive sets of markings appearing on the record strip, thereby insuring that these sets of markings are successively in registry with the recording space I8.

The recording device described thus far is disclosed and claimed in copending Nielsen application. Serial No. 666,261, Afiled concurrently herewith.

In order for a recording device oi the type described above to be effective in providing the necessary purchase data, it is desirable that the purchaser be reminded to make the necessary recordings when purchases of expendable materials such as gasoline are made. Accordingly there is provided an annoyance signal which is preferably both visible and audible and which,

g5 -as will become apparent as the following descripoutside of the housing II.

tion proceeds, is rendered effective to urge the purchaser to make the necessary recordings to terminate the annoyance signal. If desired. such annoyance signal may be mounted separately from the housing II in any suitable visible place in the vehicle. 'I'his is particularly desirable when the rec'ording device III is placed in the glove compartment of the automobile, for example. In the event that the recording device I0 is posi tioned in a visible place in the automobile the signalling means may be, as illustrated in the drawings. built into the recording device I0. Specifically, a visual signal 5I is provided which is located at any suitable place so as to be visible Associated with the visual signal 5I there is preferably also provided an audible signal such as a buzzer 52 mounted within the housing II. When the audible signal 52 is mounted within the housing II a suitable grill 53 should be provided in the housing II to permit the sound to be readily transmitted outside thehousing.

In order to insure that the purchase data is recorded by the purchaser there is provided a. suitable control circuit and equipment which is associated with the recording device I0 as disclosed in Fig. 7 of the drawings. The essential parts of the recording device I0 described above which functionally coact with the control equipment are schematically shown in Fig. Z of the drawings and characterized by the same reference numerals as in the preceding figures. As was mentioned above, the present invention is specifically illustrated in connection with a recording device for recording gasoline purchases. although it is equally adaptable for use in recording purchases of other expendable materials.

Referring now to Fig. 7 of the drawings, there is illustrated the present improved statistical analysis system which essentially comprises three parts, i. e., the recording device I0, a relay unit or control equipment 53 which may be positioned at any suitable place within the associated apparatus such as 'an automobile, and a control switch unit 54 associated with the gas tank cap or the oil aperture of the automobile or other device.

The recording device I0 per se has been fully described above except for the electrical control circuits associated therewith. The spring clip 2| for holding the recording implement 2l in position is constructed in the manner shown in Fig. 5 of the drawings so that upon removal of the recording implement 28, the spring clip 2i is distorted to operate a normally open switch or contact member 8l into engagement with a grounded contact I1.

When the cover i3 of the recording device I8 is in the closed position shown in Fig. 'l of the drawings it operates a switch member 88 which is so moved as to be in electrical engagement with a contact 8l. On the other hand, when the door i3 is moved to the open position it actuates a switch member 3l to connect the lamp I8 across al source of potential such as the battery of the automobile, thereby illinninating the translucent or transparent panel I8 and consequently the recording space i8 of the recording device l0.

The visible signal Il and the audible signal 82 are connected in parallel with each other. with one terminal of each .grounded as is clearly indicated in Fig. 7 o! the drawings.

The control unit 54 speciilcally illustrated as applied to a gas tank cap but equally applicable to an oil tank cap or other container for expendable material comprises a pair of switches 8l and 32. respectively, controlled by a suitable cam member 63 associated with the gas tank cap. Removal of the gas tank cap necessitates clockwise rotation of the cam 83 as viewed in Fig. 7 of the drawings to actuate the switch 8l to the closed position in engagement with the contact M. Replacement of the gas tank cap, on the other hand, causes rotation of the cam 83 in a counter-clockwise direction with the result that the switch 62 engages the contact 85. The switches 6l and 82 are illustrated as being connected to a suitable source of battery potential, the positive terminal being indicated at I8 and the negative terminal being grounded.

The relay unit 53 comprises a plurality of circuit conditioning rel-ays 61, 68 and 88, a slow release resetting relay 10 and a time delay relay 1I. The relay 61 controls a normally open sealin or lock-in contact 61a and a normally open contact 61h. The relay 88 controls a pair of normally open contacts 88a and 68h, respectively.

The relay 88 also controls a pair of normally open contacs 69a and 89h, respectively. The slow re- L lease resetting relay 10 controls a pair of normally closed contacts 18a and 10b, while the time delay relay 1I controls a pair of normally open contacts Ha and 1lb, respectively. Preferably the relays 81, 88 and 88 are instantaneous relays both when energized and deenergized with reference to operation of their respective contacts. The relay 1l is illustrated as a dash pot relay as evidenced by the dash pot 12, and when energized, closes its normally open contacts 1 la and 1lb only after a predetermined time delay. Upon deenergization, however, the relay 1i substantially instantaneously releases to open'its contacts 1Ia and 1lb, The relay 18 is preferably of the type which, when energized, instantaneously opens its normally closed contacts 10a and 10b but whendeenergized, closes these contacts after a short time delay relative to the instantaneous release type relays 61, 88, 89 and 1 I. By means of its normally closed contact 10b, the relay 10 controls the potential supplied to the relays81, 68, B9 and 1I. As illustrated, the positive terminal of the supply source indicated at 13 is connected directly to the coop- Ielnaating contact associated with the relay contact To consider the operation oi the system, when the gas tank cap is removed preparatory to replenishing the gas supply for the automobile, the cam 83 is rotated in a clockwise direction as viewed in Fig. '1 of the drawings so as to move switch 8l to the closed position, after first opening the switch l2, thereby ,connecting the positive battery terminal 88 to ground as indicated at 1| through the switch 8i, the cooperating contact 84, the conductor 1l and the winding of relay I1. Thus the relay 81 is energized to effect movement oi' the contacts 81a and 31h. to the closed position. At the contact 31a, a seal-in or lock-in circuit is completed for the relay 81, this circuit extending fromhthe ground terminal 18 through the switch 81a, the conductor 18, the conductor 11, and the contact 10b of the relay 10 to the positive battery terminal 13. By virtue of the closing of contact 81h, the control circuit is preconditioned for the subsequent control operation resulting upon replacing the gas tank cap. When this occurs, the cam I3 is rotated in a counter-clockwise direction to the position indicated in Fig. l so .that the switch 82 engages the contact 88 to encrgize the relay 68 which extends from the ground terminal 18 through the switch contact 81h, the conductor 18 and the switch 82 to the positive battery termin-al 83. Upon operatingthe relay 88 is sealed in through the seal-in contact 88a and serially arranged contact 10b of the relay 1I.

At its contact 68D, the relay 68 energizes the visual and audible signal means Il and 82, respectively, in a circuit which includes the normally closed contact 10b of the relay 10, the conductor 11, a part of the conductor 16, the normally open contact 68h of the relay 88, the conductor 82, the conductor 83, the normally closed contact 18a of the relay 10 and the conductor 84. The timing relay 1l is connected in parallel with the signal means 5l and 52 to a ground connection 88 so that energization of the relay 68 following energization of the relay 81 also causes the relay 1I i to be energized. The dash pot 12, however, preferably provides a time delay of the order of ilve minutes so that contacts 1Ia and 1lb are not closed until the elapse of this time delay period. The annoyance signal .produced by the described energlzation of the signal means 8l and 52 should cause the operator to make the necessary recordings in recording device Hl withthe resultant termination of the signalling operation. The time delay relay 1| is provided primarily to terminate operation of the signalling means after a delay of the order of five minutes or the like in the event that the signalling means is not terminated in the normal manner to be described hereinafter. This will prevent an undue drain on the battery of the automotive vehicle. In the event oper-ation of the annoyance signal means comprising the visual signal 5l and the audible signal 52 is not terminated after an operation of the order of five minutes or the like, the dash pct 12 permits the relay 1I to close its normally open contacts 1ia and 1 ib. Closing of the contact lla connects the slow-release relay 18 through its own normally closed contact 10b and the contact 1Ia of the time delay relay 1l across the battery terminals indicated as 13 and 8E, respectively, Whereupon the relay 10 is immediately energized to open its contacts lila and 10b terminating the operation of the signal means and causing immediate release of the relays 61, 68 and 1i by virtue of the opening of the normally closed contact 10b. It is desirable for the anal- 75-ysis organization to know that the annoyance signal means was terminated by a failure on the part of the purchaser to make the necessary recording and to this end a suitable counting device generally indicated at 8l may be provided which is energized to perform a counting operation upon each closure oi the normally open contact 'IIb of the time delay relay 1I. Preferably, this device is incorporated in the assembly 25.

It is anticipated that in substantially all cases the annoyance signal means, when energized, shall be terminated by the purchaser making the appropriate entries on the recording device I0. Assuming now that the annoyance signal means are energized, the purchaser will recognize that a recording should be made and will open the door I3 oi the recording device I0, thereby advancing the recording tape 36 and closing the switch 60 to energize the lamp i5 and thus illuminate the recording space. The next step in the recording operation is removal of the writing implement 20 from its position in the depression Iii where it is held by the spring clip 2i. By virtue of the construction oi the spring clip 2i, removal oi the recording implement E@ causes the switch 55 to engage its associated contact 5l, whereupon the relay 69 is energized, the battery terminal iii being connected through the normally closed contact liib of the relay lil, the conductor il, the winding of the relay (it), the conductor 8d, and the switch 55 to the grounded battery terminal 5l. Upon energization of the relay t@ its normally open contacts @da and @9b are closed. The contact Sila is a seal-in or lock-in contact and maintains energization of the relay t@ even after the writing implement 2i is fully removed and the switch '55 is opened. Inthe normal course of events, the purchaser makes the desired inscriptions on the record strip 38 and replaces the writing implement 2i). All during this time the annoyance signal means continues in operation. Upon replacing the writing` implement 2G in its position in the depression i9, the door I3 may be closed and when it reaches its fully closed position the switch 58 is moved to engage its associated contact 59, thereby to energize the slow-release relay 10. The circuit for energizing the slow-release relay 1D may be traced from the positive battery terminal I3 through the contact 10b, the winding of the slow-release relay 10, the conductors 90 and 9i, the switch 58, the contacts 89h and 69a. to the grounded battery terminal 92.

Energization of the slow-release relay l causes immediate openingof the contacts Ia and 10b with the resultant deenergization of the relays 61, 68, 69 and II as well as deenergization of the annoyance signal means comprisingthe visible signal I and the audible signal 52. It should be understood that the expression recording operation as employed in the appended claims is intended to include one or more steps of a complete recording operation. These steps might be opening the cover I3, removing the recording implement 20, making the desired inscription on the record strip 36, restoring the recording implement 2l) to its normal position, moving the cover I3 to the closed portion, etc.

In view of the detailed description included above the operation of the statistical analysis apparatus and system will be fully apparent to those skilled in the art and no further discussion thereof will be included herein. Itv will be evident, however, that a recording devicel is provided in which the desired data may be recorded, and by virtue of the described operation of the .annoyance signal means will be recorded. At the end of a predetermined period the purchaser will mail t'he self-contained transportable record assembly 25 to the analyzing organization in the mailing means provided therefor. By virtue of the interlock between the cover 23 and the transportable device '25, removal thereof is prevented until the cover 23 is opened, thereby further urging the purchaser to make a mileage entry.

While a particular embodiment of the present invention has been disclosed it is not desired that the invention be limited to the construction shown and described Iorit will, of course, be obvious that changes and modifications may be made therein without departing from the invention and it is aimed in the appended claims to cover all such changes and modiilcations as fall within the true spirit and scope of the invention.
